A 50 % increase. According to the UN, greenhouse gas concentrations are rising far too quickly to limit global warming to 1.5 C.Oceans absorb roughly 25 percent of carbon dioxide emitted from human activities annually. Carbon goes in both directions in the ocean. When carbon dioxide releases into the atmosphere from the ocean, it creates what is called a positive atmospheric flux. A negative flux refers to the ocean absorbing carbon dioxide.Ocean-based solutions, such as ocean alkalinity enhancement, increase the ocean's natural ability to remove and store CO 2.
